This invention relates to valve devices, and particularly to that type known as hydraulic conveyor valves.

The principal object of the invention is the production of a simply and elicient means for supplying water to the mouth of the dredge for the purpose of dislocating any foreign substance or clogged matter from the mouth of the dredge.

lith the foregoing and other objects in view, my invention comprises certain combination, constructions and arrangement of parts as will be illustrated in the accompaiiying drawings, described in the following` speciiication, and more particularly pointed out in the appended claims.

In the drawings:

liigure 1 is a view partly in elevation and partly in section of a valve device constructed in accordance with the present invention, while- Figure 2 is a top plane view of the same.

Figure 3 is a sectional view taken on line 23h-3, Figure l, and looking in the direction of the arrows.

Figure 4.- is a sectional view taken on line awa, Figure 1, and looking in the direction r the arrows.

Referring to the drawings by numerals, 1 designates the suction tube and 2 is the water supply pipe of a dredge. @n the in- .let end of pipe 2 is a strainer 3. A valve casing is placed intermediate the ends of pipe 2. and is attached to suction tube 1 by horizontal plate 5. The inner end of pipe 2 eii'ipties into suction tube 1,` at 6 near the inlet end of said pipe 1. Valve 7 is mounted on stem 8, in casing 4t, and said stem 8 is Arm 9 is lixedly mounted on the outer end of shaft 10. Shaft 10 extends into housing 11, which housing is formed upon tube 1. A plate l12 closes opening 13, through which opening iin 1 4. is placed, to locate it within tube 1. The upper end of lin 14 is fastened to shaft 10. A stub 15 is formed upon thetop of lin 14 and shackle bolt 16 is pivotally fastened at its lower end, to stud 15. The upper end of bolt 16 is threaded, and this threaded end extends into hood 17; hood 17 is fastened to plate 12 above the iin 14. A cover 18 is on the hood 17. A nut 19 is on the bolt 16. within hood 17 and this nut is provided with a rounded or convex lower face, to permit said nut to have a rolling action against the inner face of hood 17 when the im 1-1 moves. fr lock nut 2O is threaded on bolt 16 against nut 19. By screwing the nuts 19 and 2O down tight, the valve 7 will be locked upon its sea-t. The bolt 16, hood 17 and nuts therein also prevents the back pressure affecting iin 14 should pumping stop or cease.

lllhen the apparatus is in operation, it is submerged in a river or other stream where it desired to dredge the channel or deepen the harbor. A. high pressure suction is applied to the tube 1, so as to draw mud, sand, clay and like soft material therethrough, these elements being drawn into the tube or pipe 1 adjacent the points 6 (in the draw-- ings) and through this tube with gr .at velocity under normal conditions. lheii through said tube 1 is decreased because of clogging adjacent the intake end thereof, the .iin l-l will fall, so as to remove the valve 7 from the valve seat in casing 11s. Since the supply tube or pipe 2 is also submerged, it will be filled with water when the valve 7 is removed from its seat. The suction with in the main tube 1 will cause the water to be expelled from the supply pipe 2 and. strainer 8 into the suction pipe or tube 1 with considerable force. Since the supply pipe 2 will cause the water to be discharged into the suction tube 1 at right angles to the passage of the liquid through said tube, the water from the supply pipe 2 will strike with suiiicient force in suction tube 1 to wash away sand, clay and mud which might be elo,... The action t the intake of tube 1. ot the intlow of water into the tube 1 is similar to the manner sides of hills are sometimes washed by streams from hose lines if or changes as shall fairly fall within thel scope of the appended claims.

.Vilhat I claim is:

1. In a device of the class described, the combination of a suction tube, a supply pipe communicating with said suction tube,

ies

valve nie-uns for Closing said supply pipe, a n in Suid suction tube, a hood on said suction tube opposite to said fin, a bolt conneeted att one end to seid fin and having its other end positioned in said hood, nuts in said hood and threaded on said bolt, and means operatively connecting said n und valve means together.

2. ln a device of the class described, the combination of u suction tube provided With un opening', a plate closing said opening,

a hood on said platte, a lin in said SuctionL tube under said plate and hood, e supply pipe provided With valve ineens communi- Lew/,Wo

ceting at one end with said suction tube, an upstanding stud on said fin, a bolt pivotuliy connected ut its lower end to Suid stub und having its upper end extending through the plate und into Suid hood, it convex or rounded lztee nut threaded on Suid bolt Within seid hood, u lock nut threaded on the bolt :igeinet said first-mentioned nut, und means niovubly connecting said fin and valve ineens together.
